Data

Bayes Server allows access to data sources such as databases or spreadsheets, so that data can be managed in a standard way, but easily accessed throughout Bayes Server.

For example:

  • Set evidence on a Bayesian network or Dynamic Bayesian network through Data Explorer.
  • Run a batch of queries on a Bayesian network or Dynamic Bayesian network through. See Batch query for more information.
  • Learn the parameters of a Bayesian network or Dynamic Bayesian using a data source.
  • Write data sampled from a Bayesian network or Dynamic Bayesian network out to a data source.

Data

Standard data, as opposed to temporal data, is data that can be mapped to non temporal (standard) Variables in a Bayesian network.

This can be thought of as a table in a database, where each column refers to a Variable, and each row represents a separate unit of information, such as a Customer.

Example data:

Case Gender Age
1 Female 35
2 Male 41
3 Female 25

Temporal Data

Temporal Data is data that contains one or more time series/sequences, and can be mapped to Temporal Variables in a Dynamic Bayesian network.

Temporal data must be stored in a single table, where each Time Series/sequence is identified by a Case Id Column.

For an individual time series/sequence, each row must be labeled with a time value. For more information about the time value see Time Column.

Example temporal data:

Case Time Transition Obs1 Obs2
1 0 Cluster 0 12.4 15.5
1 1 Cluster 1 14.2 13.45
2 0 Cluster 1 9.3 8.6
2 1 Cluster 1 12.3 14.0
2 2 Cluster 1 18.2 13.5

Case

The term Case is used to refer to an individual row of non temporal data, coupled with any time series data that corresponds to that row.
